Argument after ** must be a mapping, not str in SQLAlchemy Database

I am building a FastAPI connected to a SQLite Database. The API scrapes data from the IMDB website and should send it to the database that is called by the API. The below code gives the following error at line 43: "TypeError: sqlalchemy.sql.elements.TextClause.bindparams() argument after ** must be a mapping, not str".

import uvicorn
from fastapi import FastAPI
from bs4 import BeautifulSoup
import requests
import re
from databases import Database

app = FastAPI()

@app.get("/")
async def fetch_data():

    database = Database('sqlite+aiosqlite:///project.db')
    await database.connect()

    query3 = """DROP TABLE imdb"""
    await database.execute(query=query3)

    query = """CREATE TABLE imdb (id INTEGER PRIMARY KEY, movie_title VARCHAR(100), ratings DOUBLE(1,1), year INTEGER, cast VARCHAR(100))"""
    await database.execute(query=query)

    url = 'http://www.imdb.com/chart/top'
    response = requests.get(url)
    soup = BeautifulSoup(response.text, "html.parser")

    movies = soup.select('td.titleColumn')
    cast = [a.attrs.get('title') for a in soup.select('td.titleColumn a')]
    ratings = [b.attrs.get('data-value')
    for b in soup.select('td.posterColumn span[name=ir]')]

    for index in range(0, len(movies)):
        
        movie_string = movies[index].get_text()
        movie = (' '.join(movie_string.split()).replace('.', ''))
        movie_title = movie[len(str(index))+1:-7]
        year = re.search('\((.*?)\)', movie_string).group(1)
        id = movie[:len(str(index))-(len(movie))]
      
    values = {'id':[id],'movie_title':[movie_title],'ratings':[ratings],'year':[year],'cast':[cast]}

    query2 = "INSERT INTO imdb(id,movie_title,ratings,year, cast) VALUES (:id, :movie_title, :ratings, :year, :cast)"

    await database.execute_many(query=query2, values=values)
    
    query = "SELECT * FROM imdb"
    rows = await database.fetch_all(query=query)
    print('IMDB:', rows)
    await database.disconnect()

if __name__ == "__main__":
    uvicorn.run(app, host="127.0.0.1", port=5049)

I have tried formatting the dictionary, but I still get the same error. I have tried list and map() object as well. How should I pass in a mapping object?

Where and how is this Laravel kernel constructor called? [closed]

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
